Question

I am the sole Global Administrator, I have lost access to my MFA methods and I am locked out of my tenant.

Ricardo Costa 21

Hi,

I am the only Global Administrator, I have lost access to my MFA methods and I am locked out of my tenant.

After installing the Autheticator app, the MFA appears to be working, however the sign in to the Azure portal/tenant is blocked or stuck in a loop where I don't receive the MFA prompt on my new phone

Can you help?

Thank you for reaching out to Microsoft Q&A.

I understand that you are locked out of tenant, Since you mentioned that you are the only Global Admin in the tenant, this qualifies as a tenant lockout scenario. To resolve this, we need to engage the Data Protection team via a support ticket to unblock your access.

To proceed, I will need a few details from you. As this information contains Personally Identifiable Information (PII), please share the requested details via private message only:

Please send me the detail via private message. So, we can assist you further.

Ricardo Costa hi and thx for stay with us at q&a, so yeah ur locked out for real

new authenticator didnt replace old MFA, tenant still waiting for old device > thats why loop

since ur the only Global Admin > no self-recovery, no workaround

only option = Microsoft support open tenant lockout case, prove domain ownership (DNS), they reset MFA or unblock account. after u get back in: create 2nd GA + break-glass account, otherwise this will happen again

rgds,

Alex
